Horton R.P. -A- #1 (API 42-311-32813) is a well in Mcmullen County operated by Gtg Operating LLC, completed January 29, 1990.

The RRC has issued one drilling permit, issued January 15, 1990, permitted to 9,500 ft.

It was permitted by Welhausen Operating CO., Inc. and has since transferred to Gtg Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Massive Carrizo, Wilcox, Olmos.

Its lease has reported 207K barrels of oil and 1.13M mcf of gas since January 1993, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
